sorry I was really busy this week, didnt have time to look into this.
The issue seems to happen in qt6 xcb so you could try switching sddm to run on wayland, which might bypass the issue (from Arch wiki):
Create the file /etc/sddm.conf.d/10-wayland.conf
with the following content:
[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell
[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1
This requires layer-shell-qt
to be installed, preferably versions 6.x which kde neon probably has in their repos (its on 5.x on base ubuntu).
Other than that, on sddm's issue repo I found two similar issues: #1761 and #1468, though both have no resolutions yet.
yes I think you can since gimp 3.0
